Arch Plan

Use this skill when the user wants the full arch workflow, not a thin router.

Prompts in this repo are legacy references only. Do not depend on saved prompts at runtime; execute the workflow directly from this skill and its references.

When to use

• The user wants a full architecture plan or phased refactor for medium/large work.
• The ask mentions research grounding, deep dive, external best-practice research, phase planning, implementation audits, or "do the serious arch flow."
• There is already a canonical docs/<...>.md plan and the user wants to continue, implement, audit, or finish it.
• The work is cross-cutting enough that a single SSOT plan doc, call-site audit, and explicit phase sequencing materially reduce risk.
